S-92351A730 Length 4 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or outdoor wood applications
• Maximum torque transmission through the external hex drive and 3/4" head width, preventing tool slippage during high-torque installation
• Enhanced holding power with thread forming design that compresses wood fibers to create permanent, vibration-resistant connections
• Optimized wood penetration featuring a pointed tip and partial threading for reduced splitting while maintaining strong grip strength
• Heavy-duty length of 4-1/2" with 2-3/4" minimum thread engagement for secure fastening in thick wood materials
• Industry-standard compatibility with 6 threads per inch and right-hand threading for consistent performance across woodworking applications
• Regulatory compliance assurance meeting ASME B18.2.1 specifications while being RoHS 3 and REACH compliant for safe industrial use

Professional Applications & Engineering Value

This heavy-duty wood screw addresses critical challenges in wood construction and industrial assembly where vibration resistance and long-term structural integrity are paramount. The 18-8 stainless steel composition provides exceptional corrosion resistance, making it ideal for outdoor structures, marine applications, and environments with moisture exposure. The external hex drive design ensures maximum torque application without cam-out, while the thread forming action creates compressed wood fibers that resist loosening under dynamic loads. With its partial threading and substantial 4-1/2" length, this fastener delivers superior pull-out strength in timber construction, deck building, and heavy wood framing applications where reliability cannot be compromised.

Specification Summary & Compliance

This 1/2" diameter wood screw features inch system measurements with a hex head (0.344" height, 3/4" width) and external hex drive. The thread forming design creates right-hand threads with 6 threads per inch and partial threading along the 2-3/4" minimum thread length. Manufactured to ASME B18.2.1 standards for dimensional accuracy and performance, the screw is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental and safety regulations for industrial fasteners.
